By the way, the inventors of the present invention have found that when a wear having a moisture permeable membrane provided on one side of various knitted fabrics (knitted fabrics) to increase moisture permeability is produced, the moisture permeable membrane may stain or transfer color when the wear is worn. I noticed it happens.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wear having a laminate comprising a knit fabric and a moisture-permeable membrane, in which the moisture-permeable membrane is less susceptible to staining and color transfer.

In order to solve the above problems, the present inventors made prototypes of various knitted fabrics, and conducted a test in which each knitted fabric was provided with a moisture permeable membrane, and compared and examined the degree of stain adhesion and color transfer to the moisture permeable membrane. . As a result, the knit fabric having the front side and the back side has a first knit structure region and a second knit structure region, and the front side is a boundary between the first knit structure region and the second knit structure region. The knitted fabric has a step on the front side, and has no step at the boundary between the first knitted structure region and the second knitted structure region on the back side, or has a step with a smaller height difference than the front side, and the knitted fabric has a step. The present inventors have found that if a moisture permeable membrane is provided on the back side of the garment, it is possible to suppress the adhesion of stains and color transfer to the moisture permeable membrane when the wear is worn, and have arrived at the present invention.

That is, the present invention consists of the following configurations.

Hereinafter, the wear according to the present invention will be described in detail with reference to the drawings, but the present invention is not limited to the illustrated examples, and can be appropriately modified within the scope of the above and later descriptions. It is also possible to carry out in addition, and all of them are included in the technical scope of the present invention.

The wear of the present invention has a laminate comprising a knitted fabric and a moisture-permeable membrane. FIG. 1 shows a plan view seen from the surface side of the laminate constituting the wear, and FIG. 2 is a cross-sectional view of the laminate constituting the wear. It is a sectional view. The laminate 1 shown in FIG. 2 has the knit fabric 2 and the moisture permeable membrane 3 as described above. The knitted fabric 2 is a general term for fabrics made by knitting threads, and the knitted fabric 2 has a front side 4 and a back side 5 .

As shown in FIG. 2, there is a first step 8 at the boundary between the first knitted structure region 6 and the second knitted structure region 7. At the first step 8, the first knitted structure region 6 is stepped. , and the second knitted structure region 7 constitutes a lower step. Further, on the back side 5 , a second step 9 having a smaller height difference than the first step 8 is provided at the boundary between the first knitted structure region 6 and the second knitted structure region 7 .

The knitted fabric 2 has at least a first knitted region 6 and a second knitted region 7 . At least one of the first knit structure region 6 and the second knit structure region 7 can be formed in a strip shape, a wave shape, a rectangular shape, a mesh shape, or a zigzag shape when viewed from the surface side of the laminate 1. More preferably, both the region 6 and the second knitted structure region 7 are formed in a band shape. In FIG. 1, both the first knitted structure region 6 and the second knitted structure region 7 are formed in a strip shape. The plan view seen from the surface side is shown, the first knit structure region 6 is rectangular when viewed from the surface side of the laminate 1, and the region where the first knit structure region 6 is not formed is the second knit structure. It is region 7. Moreover, FIG. 4 shows a further modification of the planar shape of the laminate constituting the wear according to the embodiment of the present invention. FIG. 4 shows a plan view of the laminate viewed from the surface side 4, and both the first knitted structure region 6 and the second knitted structure region 7 are formed in a wave shape.

The wear of the present invention preferably includes a region in which the length of the first step 8 in the extending direction is 10 cm or more in the 5 cm×5 cm region of the knit fabric 2 . It is more preferably 15 cm or more, and still more preferably 20 cm or more. When a plurality of first steps 8 are present within a 5 cm×5 cm area, the length in the extending direction of the first steps 8 is summed up to obtain the total length. For example, a second knitted region 7 that is 2 cm wide and 5 cm long in a region that is 5 cm wide and 5 cm long, a first knitted region 6 that is 1 cm wide and 5 cm long, and When the second knitted structure regions 7 having a width of 2 cm and a length of 5 cm are arranged in order, the length of the first step 8 in the extending direction is 10 cm.

As long as the boundary between the first knitted structure region 6 and the second knitted structure region 7 has the first step 8, the types of structures of the first knitted structure region 6 and the second knitted structure region 7 are not particularly limited. However, any knitting method may be used as long as it is a knitted fabric. For example, the first knitted structure region 6 and the second knitted structure region 7 each include a raschel structure, a tricot structure, a jersey structure, a garter structure, a smooth structure, a rib structure, a flat structure, and the like. The first knitted structure region 6 and the second knitted structure region 7 may have the same structure or different structures, but it is preferable that they have different structures. , the second knitted texture region 7 is more preferably a flat texture.

In the first knitted structure region 6 and the second knitted structure region 7, the knitting density in the course direction is not limited, but for example, 30 to 200 threads/inch (2.54 cm), and the knitting density in the wale direction is not limited. However, it can be, for example, 20 to 60 lines/inch (2.54 cm).

The size of the step at the boundary between the first knitted structure region 6 and the second knitted structure region 7 is also due to the density difference between the first knitted structure region 6 and the second knitted structure region 7 . For example, in the first knitted structure region 6, the knitting density in the course direction is, for example, 100 to 200/inch (2.54 cm), and the knitting density in the wale direction is, for example, 40 to 60/inch (2.54 cm). On the other hand, in the second knitted structure region 7, the knitting density in the course direction is, for example, 30 to 80 lines/inch (2.54 cm), and the knitting density in the wale direction is, for example, 20 to 35 lines/inch (2.54 cm). Then, when the first knit structure region 6 is dense and the second knit structure region 7 is sparse, the first step 8 is formed even if the first knit structure region 6 and the second knit structure region 7 have the same structure. It is formed. In the case of jacquard knitting, even if the knitting density in the course direction and the wale direction is the same in the first knitted structure region 6 and the second knitted structure region 7, the stitches in the first knitted structure region 6, which is a high elongation portion, are As a result of loosening and increasing, the first step 8 is formed.

In FIG. 2, both the first knit structure region 6 and the second knit structure region 7 are illustrated as being flat, but in reality, both the first knit structure region 6 and the second knit structure region 7 are flat. Since it is a knitted fabric, there are many unevennesses caused by one stitch of yarn, but in this specification, the unevenness caused by one needle of yarn is not regarded as a step.

When the first knitted structure region 6 and the second knitted structure region 7 are formed in a belt shape, when the width of the second knitted structure region 7 which is the step down is wider than the width of the first knitted structure region 6, the knit If the moisture permeable membrane 3 is arranged on the surface side 4 of the fabric 2, the belt-like dirt shape will appear clearly. Although it is not necessarily clear why the strip-shaped dirt shape clearly appears when the width of the second knitted structure region 7 is wider than the width of the first knitted structure region 6, the width of the second knitted structure region 7 is the Compared to the case where the width is narrower than the width of one knitted structure region 6, the surface of the moisture permeable membrane 3 (the side opposite to the knitted fabric 2) reflects the stepped shape of the underlying knitted fabric 2, and a large step is likely to be formed. it is conceivable that. When the width of the second knitted structure region 7 is about the same as or narrower than the width of the first knitted structure region 6, the belt-like dirt shape is not clearly defined, and color transfer and dirt adhere as a whole. state.

The width of the first knitted structure region 6 can be, for example, 1 mm or more and 30 mm or less. 2 mm or more and 25 mm or less, or 3 mm or more and 20 mm or less. When the second knitted structure region 7 is formed in a strip shape, the width of the second knitted structure region 7 can be set to a value wider than the width of the first knitted structure region 6, for example, 3 mm or more and 60 mm or less. It can be 4 mm or more and 50 mm or less, and further 5 mm or more and 40 mm or less. Especially when the widths of the first knitted structure region 6 and the second knitted structure region 7 are within the above range, the moisture permeable membrane 3 is formed on the front side 4 of the knitted fabric 2 or the moisture permeable membrane 3 is formed on the back side 5. This is because the degree of staining or color transfer on the moisture permeable membrane 3 varies significantly depending on whether it is formed.

In FIG. 2, the back side 5 has a second step 9 with a smaller difference in height than the first step 8 at the boundary between the first knitted structure region 6 and the second knitted structure region 7. From the viewpoint of avoiding staining and color transfer to the wet film 3, the second step 9 is preferably as small as possible, and there is no step at the boundary between the first knitted structure region 6 and the second knitted structure region 7. It is more preferable not to have the second step 9 (not to have the second step 9).

The knit fabric 2 may have texture regions other than the first knit texture region 6 and the second knit texture region 7. For example, in FIG. It shows a plan view of the laminate 1 viewed from the surface side 4 of yet another modification, which includes a third knitted structure region 10 in addition to the first knitted structure region 6 and the second knitted structure region 7 . In FIG. 5, when viewed from the surface side 4 of the laminate 1, the first knitted structure region 6, the second knitted structure region 7, and the third knitted structure region 10 are set as one set, and the set is repeatedly arranged in the knitted fabric 2. Yes, the first knitted structure region 6, the second knitted structure region 7, and the third knitted structure region 10 may all be band-shaped.

The texture region other than the first knit texture region 6 and the second knit texture region 7 is not particularly limited. be done. The texture regions other than the first knit texture region 6 and the second knit texture region 7 have the same step as the second step 9 or the step difference with the second knit texture region 7 on the back side 5. It is preferably smaller than the second step 9 . On the other hand, for the texture regions other than the first knit texture region 6 and the second knit texture region 7, the difference in level between the first knit texture region 6 and the second knit texture region 7 on the surface side 4 is not particularly limited. It may be larger than the first step 8 , may be the same as the first step 8 , or may be smaller than the first step 8 .

A moisture permeable film 3 is laminated on the back side 5 of the knit fabric 2. - 特許庁The moisture-permeable membrane 3 is not particularly limited, and may be a porous resin membrane or a moisture-permeable non-porous resin membrane. is preferred. When there is a second step 9 at the boundary between the first knitted structure region 6 and the second knitted structure region 7, the moisture permeable membrane 3 also has a step. Since the laminate is heated and compressed to bond the moisture permeable membrane 3 to the back side 5 of the knit fabric 2 , the step formed in the moisture permeable membrane 3 is smaller than the second step 9 .

The porous resin membrane is a membrane provided with a large number of pores through which water vapor can pass, and examples of methods for providing pores include stretching, needle punching, laser perforation, mechanical foaming, chemical foaming, wet solidification, and the like. is mentioned. The resin constituting the porous resin film is not particularly limited, and examples include polyethylene, polypropylene, polyvinyl chloride, polytetrafluoroethylene, polystyrene, acrylic resin, polyester, EPDM, urethane resin, polyvinyl alcohol, triacetyl cellulose, and the like. be done.

The resin constituting the moisture-permeable nonporous resin film is not particularly limited as long as the resin itself is moisture-permeable. Polyurethane resin is preferred.

In the wear of the present invention, a fabric (not shown) may be provided as an inner fabric on the side of the moisture permeable membrane 3 on which the knit fabric 2 is not laminated. The step formed in the moisture permeable membrane 3 is smaller than the second step 9 and much smaller than the first step 8, or the moisture permeable membrane 3 does not have a step, so that the color of the fabric is changed. Color transfer to the film 3 can be prevented.

Color transfer when a black inner fabric is laminated on the moisture permeable membrane 3 will be described with reference to FIGS. 6 and 7. FIG. FIG. 6 shows a photograph after wearing the wear according to the embodiment of the present invention, and FIG. 7 shows a photograph after wearing the wear according to the comparative example of the present invention. The photograph shown in FIG. 6 shows that color transfer does not occur when wearing the wear of the present invention in which a moisture-permeable film is provided on the back side of the knit fabric and a black fabric is further laminated. On the other hand, in the photograph shown in FIG. 7, since the wear has a moisture-permeable membrane on the surface side having the first step and is further laminated with black fabric, color transfer occurs when the wear is worn. be.

In the wear of the present invention, it is preferable that the layered body constitutes sleeves. The sleeves are visible to the wearer when the wearer puts on and takes off the garment. Wear in which the laminate forms the sleeves is preferable in terms of appearance because the sleeves are less likely to be soiled or stained.

The wear of the present invention preferably has a body portion of mesh knitting structure. Moisture permeability can be improved also in the body part by making the body part into a mesh knitting structure.

A method for manufacturing a laminate comprising a knit fabric and a moisture-permeable membrane and a method for manufacturing a wear will be described below.

A method for manufacturing a laminate composed of a knitted fabric and a moisture permeable membrane includes a preparation step of preparing a knitted fabric, a laminating step of laminating a moisture permeable membrane on the back side of the knitted fabric, and a laminate composed of the knitted fabric and a moisture permeable membrane. and a heating compression step of heating and compressing the As shown in FIG. 2, the knitted fabric has a first knitted structure region and a second knitted structure region, and has a front side and a back side. A first step is provided at the boundary between the second knit structure region and, on the back side, there is no step at the boundary between the first knit structure region and the second knit structure region, or the first step is present. It has a second step with a smaller height difference than the .

Preferably, in the preparing step, the first knitted textured region and the second knitted textured region are manufactured from a single raschel fabric using a single raschel machine. By using a single raschel machine to produce a single raschel fabric, different tissue regions can be knitted into a single fabric.

In the laminating step, it is preferable to laminate a cloth-like or sheet-like resin film on the back side of the knit fabric. The resin constituting the resin film may be a thermoplastic resin or a thermosetting resin. In the heating and compression step, the resin is heated and melted without a curing reaction, and then pressurized and compressed to shape. A thermoplastic resin is preferable from the viewpoint that the molding time can be shortened. In the heating and compression step, the resin may be heated to a temperature higher than the melting temperature of the resin forming the resin film, and the pressure may be applied to such an extent that the melted resin adheres to the knit fabric.

In the case of wear in which a layered body composed of a knitted fabric and a moisture-permeable membrane constitutes a sleeve portion and a mesh knitting structure is used in the body portion, the region of the mesh knitting structure, the first knitted structure region, and Preferably, both of said second knitted regions are single raschel fabrics.
